Q

what happens when body temperature gets out of homeostasis?

A

Body temperature regulation is maintained by homeostatic mechanisms. The set point tells what the value should be. When body temperature becomes too high, thermoreceptors send signals to the control center. The hypothalamus detects deviation from the set point and signal effector organs. The skin blood vessels dilate, which increase skin blood flow, and sudoiferous glands secrete. Body heat is lost to surroundings. When body temperature becomes too low, thermoreceptors send signals to the control center. The hypothalamus detects deviation from the set point and signal effector organs. Skin blood vessels constrict, which decrease skin blood flow, and sudoiferous glands remain inactive. If body temperature continues to drop, the control center signals muscles to contract involuntarily, and the muscle activity generates heat. Body heat is conserved.

122
Q

steps to maintain body temp at 98.6 if it falls below

A

below: person is exposed to cold and temp begins to drop, the temp receptors sense this change and the temp control center triggers heat-generating and heat conserving activities, muscles are stimulated to contract involuntarily, called shivering. this contraction produces heat, which helps warm the body. at the same time, blood vessels in the skin are signaled to constrict so that less war blood flows through them, in this way, deeper tissues retain heat that might otherwise be lost

123
Q

steps to maintain body temp at 98.6 if it falls above

A

above: person is overheated, brain’s temp control center triggers a series of changes that promote loss of body heat. sweat glands in the skin secrete perspiration, and as this fluid evaporates from the surface, heat is carried away and skin is cooled. at the same time, the brain center dilates blood vessels in the skin. this action allows more blood carrying heat from deeper tissues to reach the surface where the heat is lost to the outside, the brain stimulates an increase in heart rate, which sens a greater volume of blood into surface vessels, and an increase in breathing rate, which allows the lungs to expel more heat-carrying air
